Mecca and many old Arabic religions
Religion is one aspect most people are attached to and practised in many countries (though the night be different).
Regarding the aspect related to the religion, almost every Arab tribe had their own gods or demons, they often worshiped objects in the form of stones or trees or even celestial bodies: molyti shrines, in fact, were built on the hills because there they celebrated the cult of lunar deities. The statues of various deities were also kept in recent sacred places within the small towns that rose in the desert or along the caravan routes.
The most important of these sanctuaries stood in the center of the holy city of Mecca. Annually Arabs made pilgrimages to their holy city, suspending for the occasion every conflict.
In the same sacred enclosure that welcomed all of their gods was also the Kaaba, which is a cube-shaped building designed to preserve the so-called "black stone" (probably a meteorite): it was said that it had fallen on the earth by God's will and that , as originally it was white, but had turned black because of the sins of men.
